Information about Pyroxenite

Rocks are naturally occurring solids which are composed of minerals & have been used by humans since ages. From Stone Age, rocks are used for various purposes. Also, the metals and minerals found in rock play an important role in our life. Get to know all the Pyroxenite Uses. We have provided you with all information about Pyroxenite rock here. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Pyroxenite is white, greenish white or grey.
